If you can wait a few days, I would recommend waiting for the official 0.9.7 openssl beta which will probably solve the problem. If you can't wait, here's a patch: http://openvpn.sourceforge.net/patch/openssl097.patch Remember, 0.9.7 is pre-beta at this point so you're on your own. I have not extensively tested this patch other than a brief test to confirm that it fixed the EVP incompatibility. James
